Description
As a certified reference material (CRM), (4-(Ethylsulfonyl)phenyl)hydrazine hydrochloride meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
(4-(Ethylsulfonyl)phenyl)hydrazine hydrochloride (CAS 1171829-49-4) is a high-purity analytical reference standard with the molecular formula C8H12N2O2SHCl and a molecular weight of 236.71 g/mol.
Based on its molecular formula C8H12N2O2SHCl, (4-(Ethylsulfonyl)phenyl)hydrazine hydrochloride contains an amide group, a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 236.71 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
